TRUCK.

SPECIFICATION forming part of Letters Patent No. 410,164, dated September 3, 1889. Application filed Jun11,1889. Serial No. 313,912. (No model.)

To (0 whom it may concern.-

Be it known that I, EDWARD WILLIAM M AC- KENZIE HUGHES, of Chicago, Cook county, State of Illinois, have invented a new and useful Improvement in Trucks, of which the following is a full, true, and exact description, reference being had to the accompanying drawings. a v

This invention relates to an improved truckframe especially adapted for railroad ears or locomotives; and it consists in making the side frames and end frames of such truck of one integral piece of steel, which may include likewisethe pedestals.

My invention .will be readily understood from the accompanying drawings, in which Figure 1 represents an isometrical perspective; and Fig. 2, a section through the center of the pedestal, showing the metallic structure at that point.

My structure is made of a single piece of metal-by preference of steel-pressed between dies into the shape indicated. Ablank of suitable shape to form the resulting truckframe is first out out, and then the same is pressed between diesin the manner now well known, so as to form the structure shown in Fig. 1. In this way a truck-frame is made of great strength and lightness, the inside and outside of the plate serving to form a pedestal, as shown.

In my drawings, A represents, generally, the truck; 13 B, the side frames thereof, and As indicated, when the C C the end frames.

plate is bent the two sides of it are substant-ially parallel and closed at the top. The pedestals D are formed of the two sides of the plate, while the upper part of the plate is pressed out, as shown at E, to give rigidity and a bearing-surface at that point. The 40 pedestal-frame proper may be flanged out, as shown at F, in the process of pressing, so as to form supports for the wearing-plates.

I have not in these drawings indicated the 1 method of supporting the transom, which may be done in any suitable way.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A truck-frame for vehicles, having the side frames and end frames integral, substan- 5o tially as described.

2. A truck frame for vehicles, having the side frames and end frames-integral, the said side frames and end frames being pressed from a single piece of metal into abox shape, 5 5 substantially as described.

3. The truck for moving vehicles herein shown, consisting of a single piece of pressed steel having side frames, end frames, and pedestals pressed therein, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD WILLIAM MACKENZIE HUGHES.
